Primary Wastewater Treatment: Haliburton Study
Haliburton Study
In 2012, Halliburton experimented using produced water with TDS levels of up to 285,000ppm, here are the results:
100% success rate over 59 wells and 260 stages
No production decrease vs. fresh water Avg. savings per well $70K-$100K, mostly due to reduced
truck movements
The Bottom Line: TDS Removal – why pay to remove TDS when you can
adjust fluid composition at a fraction of the cost?
TSS Removal – Proppant permeability increases by 20% when TSS is removed

Primary Wastewater Treatment: Clay Swelling
Fresh Water Causes Clay Swelling
Hydraulic Imbalance - Formations
with smectite clays swell
when fresh water is introduced
Swelling clay can result in a 2-40%
reduction in well productivity
“In heavy oil recovery, incompatible
fluids are often injected into
hydrocarbon reservoirs, which cause
clay swelling and thus impair the
formation permeability”1

Primary Wastewater Treatment: TDS
TDS Reduces Permeability
Fracture permeability through proppants suffers with presence of TSS and
Colloidal Slime
Colloids are particles ranging between 1 and 1000 nanometers (millimicrons) in diameter, yet
are still able to remain evenly distributed throughout the solution

Primary Wastewater Treatment: TSS
TSS Impedes Well Productivity
Treated produced water maintains about 20% more permeability
